- Which of the following are arguments against the expression "survival of the fittest"? Choose all that apply. (1, 2, 3, or 4 could be correct) "Fittest" implies absolute fitness, when relative fitness of one genotype compared to others is more important "Fittest" makes it sound like it is about physical fitness, when whether an individual reproduces may depend on other traits "Fittest" makes it sound like an individual will be fit in all environments, when in reality the same genotype may have different fitness in different environments Reproduction is more important than survival for transmitting genetic differences to progenyWhat does it mean that an allele increases an organism's fitness? Choose one of the following: it increases the likelihood of that organism surviving and reproducing in their current environment it increases the health and strength of the organism it increases the likelihood of that organism surviving and reproducing in ANY environmentBelow is a life table for a hypothetical organism. What is the expected lifetime reproductive success for individuals carrying the A1 allele?

- Suppose a population has two alleles at a particular locus, and individuals with different diploid genotypes at this locus have different probabilities of survival and expected offspring, as given in the table below: Genotype % Surviving to adulthood Expected offspring GG 90% 11 Gg 80% 15 gg 50% 28 Calculate the absolute fitness, W, for each genotype, and then the relative fitness, w, using the smallest absolute fitness value as your reference. Assume that the selection differential s is equal to the difference in relative finesses of the heterozygote, Gg, genotype, and the least-fit genotype. If there are 311 individuals who are homozygous for the G allele in a population of 4,659, and we ignore the effect of genetic drift, how much should the frequency of the G allele change over one generation of natural selection? (Give your answer up to four decimal places).Suppose a population has two alleles at a particular locus, and individuals with different diploid genotypes at this locus have different probabilities of survival and expected offspring, as given in the table below: Genotype Percent surviving to adulthood Expected offspring GG 90% 11 Gg 80% 15 g8 50% 28 Calculate the absolute fitness, W, for each genotype, and then the relative fitness, w, using the smallest absolute fitness value as your reference. Assume that the selection differential s is equal to the difference between the relative fitness values for the heterozygote (Gg) genotype and the genotype with the lowest fitness. (That is, s WG Wiowest ) If there are 410 individuals who are homozygous for the G allele in a population of 1,177, and we ignore the effect of genetic drift, how much should the frequency of the G allele change over one generation of natural selection? Note that this asking for an overall size of change - you should report a value greater than 0.

- Which of the following BEST describes the relationship between genotype, phenotype, traits, and the environment? O Organisms acquire traits during their lifetime that alter their phenotype. This allows individuals to better adapt to their surroundings, and to pass on their phenotypes to their offspring regardless of their genes. An organism's phenotype is largely determined by its genes, or genotype. The relationship between an organism's phenotype and its environment determines the frequency of traits in a population. O The relationship between an organism's environment and its genotype determines the type of phenotype it will develop. Phenotypes are largely determined by the environment and organisms display traits that are unrelated to their genes.A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1 A2 genotype, and 123 have the A2A2 genotype. What is the allele frequency of A1? Answer to 2 decimal places.If all of the following individuals belonged to the same generation in the same population, who had the highest fitness? O a ballet dancer who has 4 offspring and lives to be 80 years old O a golfer who has 2 offspring and lives to be 23 years old O a body builder who does not reproduce and lives to be 101 years old O a rock climber who has 10 offspring and lives to be 33 years old
